Joan Rivers Booed For Slamming Adele’s Weight, Holocaust Joke [VIDEO]

David Letterman's 'Late Show' audience didn't react favorably to Joan Rivers' dig at Adele's weight, booing the 79-year-old comedian Tuesday. She added the words "Fried chicken" to the title of Adele's song 'Rolling in the Deep,' holding out her hands in a gesture that ridiculed the singer's weight.

Rivers is also catching heat for a remark about Holocaust when she commented on Heidi Klum's Oscar dress. "The last time a German looked this hot was when they were pushing Jews into the ovens.”
